Scientific paper

The ESOPO spectrograph is a key project of the Instituto de Astronomía of the Universidad Nacional Autónoma de México to upgrade its 2.1m telescope as a competitive facility for the next decade. The science goals call for a high-efficiency general-purpose spectrograph that covers, in a single exposure, the whole 3500 - 9000 Å spectral interval with a R~ 4000 spectral resolution, for the study of stellar and extended galactic and extragalactic sources. The double arm spectrograph provides R< 4000 modes, for sky-limited observations, as well as high resolution (R>~5000) modes for detailed studies under limited wavelength ranges, with minimal moving parts. The instrument has a variable-width 10´-long slit, but the optical design was optimized also to for multi-object masks and direct imaging. This poster summarizes the ESOPO specifications and requirements, as well as some design details of this highly efficient and stable spectrograph, showing the capabilities that substantially increase the scientific grasp of a moderate aperture telescope.
